It's a view of the page as anyone else would see it, so you can thoroughly check how it appears to other people. At the upper left side of this page is a link to another view that I recommend checking out. Now you see your available and booked appointment slots. Click on it, and a calendar event preview shows with an option to open the booking page. When you save your work, you go back to your Calendar page and see a new entry in your calendar that indicates you have available appointments.
